The end of the centuary is only 80 years away, or ~4 human gereations. There are humans alive today that will experience it. In geological time, that is practically nothing. The artivle you are refring to also says that the current rate of extinction is 10-100x that if previus mass extinctions. Unless you have some reason to believe we will manage to stop the ongoing ectinction event, then it will be a mass extinction by the time it is done; hence saying that we are in it.
